Windows 7 64 bit

Do windows 7 64 bit uses more ram than windows 7 32 bits? Do i see performance degradation if i upgrade to windows 7 64 bit?

The 64-bit versions can address more memory than the 32-bit versions (in other words, the 4GB memory address space limit, which includes I/O devices, is removed). You are effectively limited to the memory capacity of your motherboard. As for upgrading, this is not possible, sorry. When going from 32-bit to 64-bit (or vice-versa), it needs to be a clean install due to the different architecture involved. I myself have not noticed any difference performance wise between 32-bit and 64-bit.

if you have more than 4G RAM - you will notice the difference.. 64-bit runs smoother..

I'd be inclined to disagree. For a while me and my buddy had the exact same system only his was 32 bit and mine 64. I could see no difference what so ever.

How so? I'm not saying your wrong, but I've never seen my RAM usage go over 2 1/2GB. I mean, when you see systems that have like 6 or 8GB do they ever get the use out of it?

Turns out that too much free memory is not a good thing. Unused memory is wasted memory today (since Vista).

That said, too little is not good either. Monitor your memory use and buy memory sizes accordingly.

Yes, the code is a bit bigger and takes more space in memory. In addition, the installation on the hard drive is a bit bigger as well due to having to have the 64-bit support and the backward support to 32-bit.

It's unlikely, unless you have a very small amount of RAM. At the same time, you likely won't see much performance gain either....

I'll throw my hat in on the side of "smoother". My laptop system (with Windows 7 Ultimate 64-bit) alongside my office development box running Windows 7 Ultimate 32-bit definitely has a smoother "feel" to it. 64-bit (once things are cached up, that is) just "clicks".

Let's put it this way...when I'm running my 3d software, THEN I notice the jump in performance from 64-bit with 6GB memory from 32-bit with 4GB.
